Why Railway Is Safe But Not Secure
Security Of Railway Communication Protocols
The railway communication network looks different from your standard corporate IT. Its hardware, software and protocols have many peculiarities since it is an old, distributed, fragmented and highly standardised system. This creates problems when trying to introduce state-of-the-art IT security, and then there is the mindset: "But we always have done it this way!"
Although railways are one of the safest means of travel, they are not the most secure. What are railway engineers and IT experts fighting about? We will elaborate on the terms: Sicherheit, safety, security, and funktionale Sicherheit; and their implications.
The first railways were closed systems where employees had visual contact with the equipment. With the increasing amount of software and network growth, IT security is becoming a major concern. On the other hand, railway systems are made from various components with real-time and dependability requirements, and proprietary protocols, resulting in some security via obscurity. The main difference from other systems is the high degree of standardisation necessary for obtaining a permit. Consequently, changes take time and effort, resulting in the longevity of protocols.
This talk explains railway-specific protocols, such as GSM-R, RaSTA, and ETCS/ERMTS, their security model and known attacks. Nothing of this is new, but still, it is widely unknown.
So, join the talk, have fun, and learn how to stop a train - which is much simpler than starting one.

Hardware hacking tooling for the new iPhone generation If you've followed the iPhone hacking scene you probably heard about cables such as the Kanzi Cable, Kong Cable, Bonobo Cable, and so on: Special cables that allow access to hardware debugging features on Lightning-based iPhones such as UART and JTAG. However with the iPhone 15, all of those tools became basically useless: USB-C is here, and with that we need new hardware and software tooling. This talk gives you a brief history of iPhone ...

Tesla's driving assistant has been subject to public scrutiny for good and bad: As accidents with its "full self-driving" (FSD) technology keep making headlines, the code and data behind the onboard Autopilot system are well-protected by the car manufacturer. In this talk, we demonstrate our voltage-glitching attack on Tesla Autopilot, enabling us root privileges on the system.

Imagine discovering a zero-click attack targeting Apple mobile devices of your colleagues and managing to capture all the stages of the attack. That’s exactly what happened to us! This led to the fixing of four zero-day vulnerabilities and discovering of a previously unknown and highly sophisticated spyware that had been around for years without anyone noticing. We call it Operation Triangulation. We've been teasing this story for almost six months, while thoroughly analyzing every stage of ...

Elektronische Arbeitsunfähigkeitsbescheinigungen (eAU), Arztbriefe, medizinische Diagnosen, all diese sensiblen Daten werden heute mittels KIM – Kommunikation im Gesundheitswesen – über die Telematikinfrastruktur (TI) verschickt. Aber ist der Dienst wirklich sicher? Wer kann die Nachrichten lesen, wo werden die E-Mails entschlüsselt und wie sicher ist die KIM-Software? Im Live-Setup einer Zahnarztpraxis haben wir Antworten auf diese Fragen gesucht.

This talk will present details of the TETRA:BURST vulnerablities - the result of the first public in-depth security analysis of TETRA (Terrestrial Trunked Radio): a European standard for trunked radio globally used by government agencies, police, military, and critical infrastructure relying on secret cryptographic algorithms which we reverse-engineered and published in August 2023. Adding to our initial disclosure, this talk will present new details on our deanonymization attack and provide ...

We present an analysis and recovery method for files encrypted by Black Basta, the "second most used ransomware in Germany". We analysed the behaviour of a ransomware encryptor and found that the malware uses their keystream wrongly, rendering the encryption vulnerable to a known-plaintext attack which allows for recovering affected files. We confirmed the finding by implementing tools for recovering encrypted files. We have made our tools for decrypting files without access to the actual key ...
